"Unexpected issue" popup message

[Jean-Marc Roussel]

Hi all,

From time to time (not always) when connecting to the client page, I get the following popup message.

    "Unexpected Issues

    The operation could not complete due to unexpected issues.

    No error information provided"

(Here below the message in french)

In config.php, I set the Debug mode to "TRUE" and got this as log file:

As you can see, only "warnings"... What could be the problem?

The tool worked perfectly at the beginning, but the problem happens since a couple of days...

It seems that the problem could be linked with cookies...

When I remove them for my website, it works well during some time, then the problem happens again.

[Jean-Marc Roussel]

My appointment system can be called using :

• https://www.mysite.com/rdv -> system seems working by now
• https://mysite.com/rdv -> "Unexpected Issues" pop-up message

[RESOLVED] - The problem is linked to the missing "www" prefix in the URL.

[Mn So]

Just to clarify,

your BASE_URL definitions:

During error: 'https://mysite.com/rdv'

Error fixed by changing to 'https://ww.mysite.com/rdv'?

I only ask because I'm receiving the same error loop issue, but my BASE_URL has ALWAYS been defined as 'https://www.mysite.com/schedule', and it HASN'T fixed the problem for me yet.

Any other ideas?

[Mn So]

OH OH OH I think I get it.  Are you saying that BECAUSE the base url is defined as https://www.mysite.com/etc, then the URL used to access the appointment system MUST ALSO be accompianied by www. prefix in the ADDRESS BAR, instead of simply https://mysite.com/etc?

[Jean-Marc Roussel]

Yes, that's correct !

And because some web browsers hide the "www" prefix in the address bar, this leads to some confusion in the URL to be used to access the appointement system.

Now I've just configured my website to have the reverse situation :

1. in .htaccess file, I've added a rewrite rule on port 80 to redirect the "http" requests to "https://mysite.com/$1" (WITHOUT the www prefix),
2. in "config.php" file in EA folder, I've set de BASE_URL to "https://mysite.com/ea_folder"
3. And to be sure, I've also deleted the cookies of the "mysite.com"
   

The only not working situation is when the user manually enters "https://www.mysite.com/ea_folder". But I just have to avoid promoting that wrong address...

[RESOLVED]

In order to close this subject, I've added the following lines in my .htaccess file:

    RewriteCond %{HTTP_HOST} ^www.mysite.com$

    RewriteRule ^(.*) https://mysite.com/$1 [QSA,L,R=301]

Now it works perfectly with or without the "www" prefix ! :-)
